Gravity racers descend on Mount Panorama

The three day event draws international and local competitors in action sports including street luge, skateboarding, scooter, BMX and downhill mountain biking.

Bathurst street luge rider Mark Anderson will be making his premiere appearance on the track this year.

"I got into this through some friends - they knew I was into the more obscure sports and I already had some gear because I ride motorcycles as well. A mate went overseas and so I ended up with his board. I'm looking forward to heading down the mountain for the first time," says Mark.

ABC Open producers Luke Wong and Ana Tovey will also be there working with contributors for the ABC Open 110% sports video project.
